Connection breaks (becomes red) with the printer
Hi, I have Repetier-Server installed on Windows 7 Ultimate. I have two printers which are installed in two usb-ports. Printers are visible and seem to bee functioning in Windows Device manager. I have checked the ports are configured in RS according to ports in device manager. I have also tried with new usb-cables. My printers use Andciv CM3E 3D printer control boards (a little fancy hardware from China). The printer works very well in Cura, Slic3r, Simplify3D. I haven't seen any connection problems with those software.
My problem is as follows: The connection between printer and RS drops down after few minutes when the printing process is idle. Sometimes I get the connection back on if I unplug the usb-cable or reboot the printer. Once I managed to print and control those two printers together for 24 hours when I finally got the printing to start.
